Title:
  Nova should not return a 500 on floating ip create with ipv6

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Neutron does not support creating or using floating ips on an ipv6
  network. When nova gets a create floating ip call and does the
  passthrough call to neutron it will get a 400 response from neutron
  saying there is not ipv4 subnet available. This goes unhandled by nova
  and will cause a 500 response. Since this is an expected error, nova
  should catch it and return a 400 to the user for the same reason.

  For example logs with the unhandled exception see:
